Specification of Letters Patent.

Patented Aug. 1, 1911.

Serial No. 614,176.

To all whom it may concern:

Be it known that I, CHARLES Pn'roCK, a citizen of the United States, andresident of Chicago, Illinois, have invented certain new and usefulImprovements in Packless and Quick-Acting Valves; and I do herebydeclare that the following description of my said invention, taken inconnection with the accompanying sheet of drawings, forms a full, clear,and exact specification, which will enable others skilled in the arttowhich it appertains to make and use the same.

This invention has general reference to steam valves; and it isespecially directed to that class of valves in which there is no packingemployed or necessary to prevent the escape of iuid past the valve stem,and in which a condensing chamber is used to prevent the steam frominjuring the metallic diaphragm employed therein. It shall also be ofthe quick-acting type.

To this end, the invention consists in the novel and peculiarcombination of parts and details of construction as hereinafter firstfully set forth and described and then pointed out in the claims.

In the drawings already referred to,which serve to illustrate thisinvention more fully, Figure 1 is an elevation of my packless,quick-acting valve. Fig. 2 is a longitudinal sectional elevation on lineof Fig. 1, showing the valve in closed condition. Fig. 3 is a similarView, illustrating the valve in open position. Fig. L1 is a sectionalplan on line y y of Fig. 3. Fig. 5 is a like view on line e' e of Fig. 2except that the branch 13 on the valve casing is not shown externallyscrew-threaded, this construction being a modification of that shown inFig. 1. Fig. 6 is a perspective view of the operating lever by which thevalve proper is opened and closed.

Like parts are designated by the same characters and symbols ofreference in all the figures.

nallv screw-threaded to receive a bonnet B, which bonnet is centrallybored and tapped to receive the correspondingly screwthreaded part 18,of the operating spindle C, said spindle carrying at its upper end ahand wheel or similar manipulating member 141, by means of which thespindle is rotated.

The interior of the casing A is adapted to receive a tapering water potD, which pot has at its upper end a laterally-projecting flange 15,resting upon the upper edge of the casing A, and held thereto by theshoulder 16, in the bonnet B. Between the flange 15 and the shoulder 16there is located diaphragm E, which is centrally punctured for thepassage of the upper, screw-threaded end of a rod 29, as willhereinafter more fully appear.

Centrally in the water pot D there is, preferably formed integral withthe bottom of the pot, a tube 20, and over this tube is inverted a cupF, which normally reaches from the bottom of the .water pot to within ashort distance of a member or collar 19, located on the upperscrew-threaded part 17, of the rod 29, and serving as an abutment forthe cup F. In the center of this cup F there is a downwardly pendingtube 21, which tube is smaller in diameter than the tube 20, and whichis securely fastened to the bottom of the cup F.

From the bottom of the water pot D project downwardly abracket 22, andalso an arm 23, both these parts being preferably formed integral withthe water pot, the bracket 22 being designed to serve as a guide for theguiding stem 24, of the valve proper G, and the arm 23 is planned toaord a pivot member for a lever 25, shown in detail in Fig. 6, saidlever having at one end a fork 26, engaging the valve-stein 2&1, itsopposite end being pivotally connected to the bifurcated lower end 27,of said arm 23, there being near this end of the lever 25 an upwardlyprojecting punctured lug 28, wherewith connects' the lower end of thebent rod 29, by two links 30, said bent rod 29 forming, as it were, adisconnected con-V tinuation of the screwnspindle C.

Above the diaphragm E there is located a connecting member 31, being acylindrical body bored and internally screw-threaded to receive a collar32 at the lower end ofthe spindle C, and a follower or retaining sleeve33 above said collar to rotatably connect said spindle C to saidconnect-ing member, said latter member being also internallyscrewthreaded below the collar 32, to receive the upper, screw-threadedend 17 of the bent rod 29.

The diaphragm E comprises preferably a number of superposed metallic,corrugated, disks, whereby said diaphragm is made of sufficientsti'ength to resist high pressure, but at the same time very flexible tooffer but slight resistance to the bending thereof, and also to avoidbreakage caused by the frequent bending or deflecting of said diaphragm.These several layers of the diaphragm are held together and totheconnect` ing member 31 by the collar' 19 which acts as a clamping nutfor the parts mentioned. In the lower pai't of the casing A there islocated the usual valve seat 34, upon which the valve proper G seats,said valve proper being of any eflicient and desirable construction.

rThe operation of this valve is subst-antially as follows: The valve isconnected to a line of steam pipe, a radiator, or other object wheresteam is to be turned on and off. The lhand wheel 14 is turned in theproper direction to open the valve proper Gr, by pulling the diaphragm,`and with it the bent rod and the lever upwardly. Steam will enter thecasing and pass out through the branch 18. through the space 35 betweenthe bent rod 29 and tube 21, and also through the space 36 between thelatter tube and t-he wall of the cup F and lift the latter untilarrested by the collar 19, and enter the space below the diaphragm wherethe steam will be condensed and collect as water in the water pot, fromwhich it will overflow back through the space 3G so that the diaphragmwill be comparatively cool and no steam able to pass from the chamber orcasing past the valvespindle. As soon as the pressure is released, theinverted cup F will drop back to its normal position with its innerbottom surface resting upon the upper edge of the inner tube or standpipe 20, thereby leaving a small space below the lower edge of the cupthrough which the water of condensation may pass upwardly through anotch 37, at the upper end of said standpipe 20'. This stand pipe 2O hasbel-ow the bottom 40, of the water pot an extension 20a, approximatelyof the same length as the inner tube 21 which lextends for some distancebelow said bottom 40, whereby said extension 20a, in conjunction withthe inner tube 21, acts as a siphon and causes the water in the pot' tobe discharged through the space 36 while the space in the tube 21, (35)serves as a vent to they spacel below the diaphragm E.

It will now be observed that this steam valve is packless, and thaty thevalve proper G, is operated by the lever 25 at the long Steam will alsopass arm thereof, while the rod 29 is pivoted to said lever at the shortarm 28, the proportions of the arms being as 1:4, and that the valveproper can be fully opened by approximately one revolution of the handwheel 14. It will also be noticed that this steam valve isanti-freezing, that is to say that the water of condensation in thewater pot is immediately siphoned out as soon as the valve proper isclosed, or pressure in the valve casing released. This steam valve is-especially well adapted for use on steam radiators of heating systems,but it is evident that it is also applicable to all uses and purposeswhere so-called globe valves and gate valves are now employed. I/Vhilefor the smaller sizes of this steam valve the upper portion of the valvecasing'kwould seem rather large in proportion to the remainder thereof,which has been thus planned to afford ample space for a diaphragin ofsufficient diameter and iieXibilty, and to permit of the entry of theentire interior valve mechanism through the upper end of the casing,these differences in the dimensions will become less apparent as thesizes of the valve increase. In cases where this valve is to be used inhot-water heating systems, or for cold water and other cooled fluids,where the necessity of keeping the diaphragm cool to prevent its beinginjured by heat is not prevalent, I shall dispense with the condensedwater pot and the float cup in the casing, thereby cheapening the valveto a considerable extent without detracting from its usefulness as astop valve of the quick-acting and packless type.

Having thus fully described this invention, I claim as new and desire tosecure to me by States 1. A packless and quick openingvalve, comprising,in combination, a casing, a valve proper in said casing, a bonnet onsaidy cas- Letters Patent of t-he United ing, a lifting screw tapped insaidrbonnet, a diaphragm in said casing located between` the upper endof saidcasing and the bonnet,

In testimony that I claim the foregoing as my invention, I have hereuntoset my hand in the presence of two subscribing witnesses.
